ABSTRACT:
Apparatus and method for determining a fixed point in a mobile communication system are disclosed. An initial fixed point is set through simulation and a saturation for an output of a target device is compared with a reference saturation. Then, the position of the initial fixed point is adaptively changed according to the change in the output range of the target device. Therefore, when a floating point is converted into a fixed point, the performance of the system can be improved while the complexity of the hardware can be reduced.
